CRYSTAL LAKE – A settlement was reached between Community High School District 155 and a Cary-Grove High School student after he was suspended for using a smartphone to take video of Cary's mayor speaking at the school. District 155 Board members approved the settlement Tuesday after meeting in executive session. Cary-Grove senior Matthew Ahmann alleges administrators discouraged him from speaking before Cary Mayor Mark Kownick visited one of his classes, and they later suspended him for posting recordings of the mayor’s speech online. Board President Adam Guss and Ahmann's attorney Nemura Pencyla said they could not say what was agreed to in the confidential settlement that was filed with the U.S.
